The test facility dipole magnet (TFD) is being developed at the Lawrence Berkeley National Laboratory (LBNL). This is a large-bore Nb$_3$Sn dipole magnet to be at the center of the High Field Vertical Magnet Test Facility (HFVMTF), funded by the U.S. Department of Energy (DOE) Office of Science (SC), and designed to test advanced cables and inserts in a high transverse background field and in...
Dipole magnets that approach or surpass magnetic fields of 20 T for use in future particle circular accelerators, and high-field solenoids that operate at 20 K, such as envisioned in a multi-TeV muon collider, require the use of high-temperature superconductors (HTS). Several prototype magnets based on high-current HTS CORC® cables and wires, wound from REBCO coated conductors, have been...
The Falcon D (Future Accelerator post- LHC Cos-theta Optimised Nb3Sn dipole) dipole is part of the High Field Magnet (HFM) program. CERN in collaboration with the Italian Institute for Nuclear Physics (INFN Genova and LASA Milano), is developing the design of cos theta dipole magnet beyond 11T based on proven Nb3Sn technology in the MQXF quadrupoles used in the high-luminosity upgrade of the...
The Future Circular Collider-hadron-hadron (FCC-hh) project is envisioned as the successor to the Large Hadron Collider (LHC) at CERN (European Organization for Nuclear Research). The proposed particle accelerator, with a center-of-mass energy up to 100 TeV, will be housed in a tunnel approximately 100 km in circumference, representing a major leap forward in the exploration of fundamental...
The High Field Magnet (HFM) R&D program at CERN aims to find technological solutions for the construction of accelerator magnets to be installed in future post-LHC colliders. The Italian Institute of Nuclear Physics (INFN) and CERN are collaborating to design and fabricate a new four-layer Nb3Sn cos-theta dipole able to achieve a bore field of 14 T with at least 20% of margin on the loadline....
CEA Paris-Saclay is developing, in collaboration with CERN, the R2D2 (Research Racetrack Dipole Demonstrator) magnet. The main goal is to demonstrate the feasibility of key technologies for future high field 16 T $Nb_3Sn$ magnets for particle colliders. On one hand, the coil manufacturing has been finalized and four coils have been produced. First, two practice coils have been manufactured,...
